God I Love Mods

The image was a screencap from (a clearly modded version of) Left 4 Dead 2.

Starring...
Mass Effect's Garrus Vakarian as Ellis
Halo's Master Chief as Coach
Batman and DC's Deathstroke as Nick
and Lollypop Chainsaw's Juliet Starling as Rochelle

...as they prepare to take on zombies which include...
Hunters dressed as Foxy from Five Nights at Freddie's
Tanks portrayed by the Macho Man Randy Savage (seriously, he throws giant slim jim packs)
Chargers dressed as Bouncer Big Daddies from Bioshock
and Smokers dressed as Slender Man

All possible thanks to the marvelous mania of modding!

And before anyone asks, I'm ALWAYS either Nick or Louis, depending on the campaign.
